Embodiment Construction
[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0015] as attached figure 1 As shown, as an ultra-light simple locking device for aerospace of the present invention, it is used to solve the locking problem of small and medium-sized expandable structures after deployment. The device includes a fixed seat 1, an unfolded seat 2, a locking plate 3, a rotating shaft 4, a torsion spring 5, a flat washer 6, a spring washer 7, and a nut 8. The fixing base 1 and the unfolding base 2 are respectively connected with the two parts of the expandable structure by screws, and the fixing base 1 , the expanding base 2 and the torsion spring 5 are installed on the rotating shaft 4 . The locking piece 3 is fixed on the bottom of the fixing seat 1 by a nut 8 . Utilizing the difference in structural rigidity at different positions of the locking piece 3, the flat pad 6 and the spring pad 7 are used to realize th...

The invention relates to an ultra-light type simple locking device for space navigation. The ultra-light type simple locking device comprises a fixed seat, an expanding seat, a rotating shaft, a torsion spring, a locking piece and a nut. When expanding in place, the expanding seat can be easily ejected into the inner side of the locking piece and is locked into the inner side of the locking piece due to the sufficient rigidity of a stressed part of the locking piece during the ejection, thereby realizing locking. The fixed seat is fixedly connected with an expandable structure through a bolt, and the expanding seat is fixedly connected with another part of the expandable structure; the fixed seat, the expanding seat and the torsion spring are mounted on the rotating shaft; and the locking piece is fixed at the bottom of the fixed seat through a bolt and is adjusted to a proper locking position by moving the mounting position of the locking piece. A traditional locking device is locked by virtue of a torsion spring and is generally matched with an expanded volute spiral spring for use. Compared with a traditional manner, the ultra-light type simple locking device has the advantages of simple structure, small volume, lightness, low cost, strong portability and the like and further has very wide application prospect.
Description
technical field [0001] The invention relates to an ultra-light, compact, reliable and simple locking device with strong portability, in particular to a locking device for a light and small expandable satellite antenna structure used in aerospace. Background technique [0002] Nowadays, deployable structures in the aerospace field are more and more widely used, and the essential component of the deployable structure is the deployment and locking device. The traditional deployment and locking device achieves deployment and deployment in place through the combination of scroll springs and torsion springs. Post limit purpose. This kind of mechanism is not only complex in structure, large in size, and high in cost, but the weight of a single mechanism can reach 200~300g, and it is generally used in pairs. At the same time, a CCL is connected between the two mechanisms to control the deployment trajectory. However, aerospace products have strict requirements on structural size,...
